The future of DBG: creative cost savings – Oberberg News

Wiehl – Council discusses management proposal on Tuesday – Market and financial situation make planning difficult – Can a temporary building be incorporated into the new building later?

By Lars Weber

The city council would like to outline the next important path for the future of Wiehl High School at next week’s special council meeting. At the end of August 2021, the Council decided not to build a new building on the site of the stadium. At the same time, it was decided that management should issue feasibility studies to examine the remaining three variables (OA mentioned). The results have already been submitted to the DGB working group and analyzed. The situation in the development of construction costs and the financial market had a special impact. The pandemic has already made it difficult to predict the cost reliably. The war in Ukraine exacerbated this situation.

As a reminder: an improved version of the architecture competition winner a few years ago was still under discussion, in which part of the existing building would be renovated and the rest being built from scratch. Furthermore, a new building on the present site including Wiehltalhalle, where the new grammar school was to be built gradually (the step-by-step alternative). Last but not least, a new building was commissioned on a site that was to be constructed by relocating the main road.


As per the decision formulated by the management, after assessing all the factors such as sustainability or project risks, two variables should not be pursued anymore. This includes, on the one hand, the step-by-step variable, and on the other hand, the variable in which the main road must be relocated. Among other things, both ideas have a longer project life (up to eight years instead of 6.5 years) than the optimized version of the competition solution. In addition, the list of project risks when moving the main road is very long. The original hope for a costly interim solution was dispelled by this construction strategy after analysis of the feasibility studies.

Especially in view of the difficult market and financial situation (increasing construction costs, delivery bottlenecks, interest rate evolution), the feasibility of a special temporary solution for the optimal competitive solution is now being examined. According to the draft decision, the goal is to integrate the temporary building into the new wing of the DBG. The study is based on temporary construction prospects in modular timber construction. This makes it possible to disassemble without damaging the components. In other words: Instead of spending an estimated €16 million in a container village to outsource to students, which is only eventually rented out, students should be tutored directly into a new building. Once some sections of the Grammar School are completed and ready to move into, the temporary building will be moved and reused, so to speak, in the actual new building project.

Another approach to reducing costs: it must be analyzed whether the regeneration percentage in the optimal competitive solution, which is currently around 50 percent, can be increased further and whether the space can be reduced. Even implementing the concept of restructuring could now be back on the table. Management proposes to study this in parallel with the resumption of the negotiation process with the winner of the PVMA competition. The concept of renovation has to be layered so that different degrees of regeneration are conceptualized and provided with a cost estimate. In addition, consideration should be given to setting up accessibility in the existing building and reviewing external facilities. “The renovation variant should be considered if the feasibility of an optimal competitive solution, including the use of a temporary building, is not technically feasible or not economically viable,” it continues.

Politicians will decide what the additional strategy will eventually look like on Tuesday, May 24, from 5:30 p.m. in Wiehltalhalle.
